JOSEPH OOLSON, OF BBENTWOOD, NEW YORK.

INCUBATOR.

SPECIFICATION formingpart of Letters Patent No. 245,450, dated August 9, 1881.

Application filed December 23, 1880.

To all whom it may concern:

Be it known that I, JOSEPH OOLSON, of Brentwood, in the county of Suffolk, Long Island, and State of New York, have invented a new and Improved Incubator, of which the following is a specification.

The object of this invention is to utilize to the best advantage the heat developed by the flame of the lamp by which the incubator is warmed.

In the accompanying drawings, Figure l is a front elevation of my improved incubator. Fig.2isacross-sectional elevation of the same on the line as m, Fig. 1. Fig. 3 is a longitudinal sectional elevation of the same on the line y 3 Fig. 2. Fig. 4 is a plan and horizontal sectional view of the same, showing parts of the cover, the upper section of the egg-drawer, and the intermediate section of the tank on the line 2 z, Figs. 1 and 3.

Similar letters of reference indicate corresponding parts.

The incubator is constructed throughout with double walls A A, having a layer of paper, B, tarred felt, or some similar material attached to the inner or adjoining sides. An air chamber, G, is thus formed between the two walls A A, and these chambers are in communication with the outer air by means of channels D D in the top of the incubator-box, and these chambers O O are also in communication with the interior of the incubator by means of the apertures E E intheinnerwall of the incubator. The cover F of the incubator is constructed in a like manner.

The water-tank of the incubator consists of three fiat sections, G, H, and J, arranged above each other and connected by the upright tubes K and L. The upper section, G,is of such size that its edges can rest on a strip, M, attached to the interior of the incubator a distance from the upper edge equal to the height of "the upper section so that the top of the upper section, Gr, and the top of the incubator are on a level. The section H, which is below the section G, is smaller, as it must pass by the strips M, and the lowest section, J, is considerably smaller than the other sections, but is higher, and. is provided with a central tube, N, which forms a chimney for the lamp 0, which rests on the floor of the incubator and directly below this tube N.

(NomodeL) A drawre, P, with a wire netting or other perforated bottom, contains the eggs Q, and slides in and out directly below the section G of the tank. A smaller drawer, R, containing moist earth, to provide the incubator with the required quantity of moisture, is arranged directly below the drawer P and above the section H of the tank.

Two drawers, S S, are arranged at the side of the section J of the tank, and receive the young chickens directly after they are hatched, the chickens being dried in these drawers.

A wire-netting door, T, is arranged at the bottom of the incubator, to admit a sufficient quantity of fresh air; but in cold weather a pane of glass, V, is passed into the frame of the door, behind the wire netting. The space between the outer end surfaces of the section G of the tank and the inner wall of the incubator, above the strip M, is filled in with gypsum or some suitable cement, to prevent the air from passing through this joint.

The upper section, G, of thetank is provided with a nozzle, W, through which water is poured into the tank. A piece of cloth, I, is placed over the wirenettin g bottom of the drawer P. In this incubator the water is thoroughly heated by the flame of the lamp 0, which passes up through the tube N and strikes the bottom of the second section, H, of the tank.

No heat is lost, and the incubator can be heated with a very small quantity of oil. As the water is heated in the small lower section, J, it will begin to boilvery soon, and, rising, causes a circulation of the water in the tank. The double walls and the two layers of paper protect the eggs in the incubator from the effects of sudden changes of temperature, and at the same time permit of building the incubator very light and very strong. As the air-chambers G communicate with the inside of the incubator by means of the apertures E, the chambers G will be filled with warm air.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. In an incubator, the combination, with the lamp 0, of the water-tank sections Gr H J, arranged one above another, connected by pipes K L, and the lowest provided with a central tube, N, as shown and described.

2. In an incubator, the combination, with the of-paris or cement between the sides of the tank and the inner wall, A, substantially as 10 herein shown and described, and for the purpose sct forth.

JOSEPH COLSON.
